Problems solved by technology

[0003] At present, the green control technology of important mulberry pests (such as mulberry borer, mulberry caterpillar and mulberry looper) mainly focuses on the research on sex pheromone attractants, and corresponding sex attractant products have also been obtained. However, the insect sex information researched at home and abroad The attractants of natural attractants are all male adults, and there are few reports on attractant products targeting female moths, which leads to the lack of research and application of attractants for female adults, which in turn affects the comprehensive and sustainable control of pests

Embodiment 1

[0037] Y-type olfactometer test of botanical attractants and their compositions on female mulberry borer moths

[0038] The test methods and steps are as follows:

[0039] (1) Three single products of trans-3-hexen-1-ol, n-butyl acrylate, n-hexadecane and trans-3-hexen-1-ol + n-butyl acrylate, trans- -3-Hexen-1-ol + n-hexadecane, n-butyl acrylate + n-hexadecane and trans-3-hexen-1-ol + n-butyl acrylate + n-hexadecane 4 These compositions were respectively formulated into 7 attractants of 60ug / ul according to the mass fraction of trans-3-hexen-1-ol 1.16%, n-butyl acrylate 1.49%, and n-hexadecane 4.26%.

[0040] (2) The behavior of female mulberry borer moths was measured by using Y-type olfactometer. Taking the mated female mulberry moth (2-3 days old) as the test object, the entire olfactometer measuring device was placed in an environment with uniform illumination, and the light intensity was not higher than 200 μmol / m 2 s; use a micro sampler to take 20 μL of the standard...

Embodiment 2

[0044] Synergistic effect of plant-derived attractant single product and composition on mulberry borer food attractant

[0045] The test methods and steps are as follows:

[0046] (1) Three single products of trans-3-hexen-1-ol, n-butyl acrylate, n-hexadecane and trans-3-hexen-1-ol + n-butyl acrylate, trans- -3-Hexen-1-ol + n-hexadecane, n-butyl acrylate + n-hexadecane and trans-3-hexen-1-ol + n-butyl acrylate + n-hexadecane 4 According to the mass fraction of trans-3-hexen-1-ol 1.16%, n-butyl acrylate 1.49%, and n-hexadecane 4.26%, 7 attractants were respectively formulated into 60ug / ul for treatment.

[0047] (2) above-mentioned 7 attractant treatments are combined with mulberry borer food attractant respectively, take the combination of equal amount of liquid paraffin and mulberry borer food attractant as contrast, test the above-mentioned 8 combined treatments to the field trapping effect of mulberry borer; Three replicates were set for each treatment, the number of trap...

Embodiment 3

[0051] Experiments on attracting female mulberry borer moths with different formulas of female mulberry moth ovipositing plant-derived attractants

[0052] The test methods and steps are as follows:

[0053] (1) According to trans-3-hexen-1-ol 0.15%, n-butyl acrylate 0.21%, n-hexadecane 0.54%; trans-3-hexen-1-ol 1.16%, n-butyl acrylate Ester 1.49%, n-hexadecane 4.26%; trans-3-hexen-1-ol 6.52%, n-butyl acrylate 8.67%, n-hexadecane 13.84% three mass fractions were formulated into 60ug / ul 3 attractant treatments.

[0054] (2) The above-mentioned 3 attractant treatments were placed in the mulberry orchard at an equal distance, and the same amount of liquid paraffin was used as a control to test the field trapping effect of the above-mentioned 4 attractant treatments on mulberry borer; each treatment set 3 repetitions , the number of trapped female moths was recorded regularly every day, and the lure core was replaced every 3 days; the trapping experiment was carried out from Aug...

Abstract

The invention discloses a mulberry borer female moth attractant and its preparation method and application, belonging to the technical field of pollution-free comprehensive prevention and control. The active ingredients of the mulberry moth attractant include: n-hexacane, trans-3-hexene-1-ol and n-butyl acrylate, the mulberry moth attractant has a significant attracting effect on the mulberry Effectively reduce the amount of eggs laid by female moths in mulberry fields, thereby reducing the population of mulberry borer larvae and the damage to mulberry trees, and reducing the number of traditional chemical pesticide control. Promoting the high-quality development of sericulture is of great significance and has high promotion and application value.

Description

technical field [0001] The invention belongs to the technical field of pollution-free comprehensive prevention and control, and in particular relates to an attractant for female mulberry borer moths and a preparation method and application thereof. Background technique [0002] Mulberry borer [Diaphaniapyloalis (Walker)] belongs to Lepidoptera, Pyralidae, and is one of the major pests of mulberry trees. Due to its large reproductive capacity, short reproductive cycle, obvious overlapping generations, and difficult prevention and control, it is very easy to break out into disasters under suitable conditions, which seriously affects the sustainable development of the sericulture industry. At present, traditional chemical control methods are mainly used in production to prevent and control it, and the high control effect is also accompanied by pests resistance to pesticides, environmental pollution, pesticide residues, impact on human and animal safety, and sericulture poisonin...
